Testicular cancer accounts for 1% of all male cancers yet is the most common cancer affecting men aged 15–44 years. Most testicular cancers are seminomas or non-seminomatous germ cell tumors. Rarely, multiple testicular cancers may occur simultaneously, most often of the same histological type. However, synchronous tumors of different histological types may occur, although rarely. In this case study, we present the sonographic features with histopathologic correlation in a case of unilateral synchronous testicular tumors of discordant histology.
